No LFE

[jackson1234578]

Issue where there is nothing coming out of LFE channels. Is there any fix for this. Mac OS Sonoma, Had this issue on Mojave too.

Have you ever not had this issue (i.e. did the behavior change at some point)?

I do not think this is a bug, but rather there being no LFE input (i.e. silence on the LFE input channel). Most applications do output LFE information. What application are you noticing this with?

Another thing you can try is to play around with the upmix matrix definition (in the source https://github.com/q-p/SoundPusher/blob/master/SoundPusher/SPDIFAudioEncoder.cpp#L145 ) to add some contribution of the non-LFE channels to the LFE channel. But be aware: AC3 specifies that LFE channel only contains (very) low frequencies, I don't know it will deal with with high frequency data copied from the normal channels. There is no frequency filtering anywhere in SoundPusher itself (but ffmpeg of course does some for the encoding).

Some amps can also redirect low frequencies from the normal (non-LFE) channels to the LFE speaker. That might be a work-around.
